We Never Do Evil So Effectually As

How Hollow Is The Heart Of Man, And How Full Of Excrement!

Few Friendships Would Survive If Each One Knew What His Friend Says Of Him Behind His Back.

As We Speak Of Poetical Beauty, So Ought We To Speak Of Mathematical Beauty And Medical Beauty. But We Do Not Do So; And That Reason Is That We Know Well What Is The Object Of Mathematics, And That It Consists In Proofs, And What Is The Object Of Medicine, And That It Consists In Healing. But We Do Not Know In What Grace Consists, Which Is The Object Of Poetry.

Vanity Is But The Surface.

The Heart Has Its Reasons Of Which Reason Knows Nothing.
